To strengthen the point, the Lord asks them ‘whence is he then his son?’, and we could legitimately add a word to get the sense – ‘‘whence is he then [only] his son?’ David understood the Lord’s promise to him: ‘I will set up thy seed after thee, which shall proceed out of thy bowels, and I will establish his kingdom. 13 He shall build an house for my name, and I will stablish the throne of his kingdom for ever’ (2 Samuel 7:12-13).
This is the first step in salvation. By the Holy Spirit, our eyes are opened, and we see that Christ is God, the Son of God who came to redeem, and we hold him in awe, and reverence. And we have a new view, and this realisation dawns on our minds, grows in our hearts. It brings us to our knees. It will bring us under conviction of sin. It will bring us into a realisation of our need of him, and we will run to him and yield to him.
In the walk of righteousness for God's people, it remains essential to have high in our minds and on our hearts, an appreciation of Christ and who he is, his lovingkindness and his power, his greatness, and his glory. If we are children of God and we are converted to him, one day we shall see them. We shall see him if we die before his return. We shall see him, of course, if we are alive at his return, and we will be overwhelmed. ‘I never realised’, we will say, ‘his Majesty and his glory.’ When we see the glorified Lord, when we see the God man, we shall just be amazed and overwhelmed. And if it were possible – and happily it may not be possible – we will be deeply ashamed that, as Christians, we treated him so lightly, and prayed to him so flippantly at times. These things are just beyond our comprehension at the moment. But to do our best, to keep him in view. David calleth him, Lord, and so must we.
